The small toothed sprocket on the gearbox output shaft: it is what drives the chain.
JT SPROCKETS offers this front sprocket for KAWASAKI KMX 125 2002. The front sprocket sits on the gearbox output shaft and passes the engine’s power to the chain, which turns the rear sprocket and the rear wheel.
The benefits:
Dished or hooked teeth: replace it straight away, otherwise it will ruin a new chain within hours.
Cross-Mania tip: Replace the front sprocket together with the chain and rear sprocket, renew the sprocket nut or circlip and check the output shaft seal.
